What is JMX and how it works?

JMX Monitoring is done by querying data from “Managed Beans” (MBeans) that are exposed via a JVM port (JMX console). An MBean represents a resource running inside a JVM and provides data on the configuration and usage of that resource. MBeans are typically grouped into “domains” to denote where resources belong to.
